Wonderful! You saved me a good headache!

Here is my/your final code, hope someone finds it useful!

/* When a ACF "Featured article" (in 71% articles) is set to true, all the rest are updated to false */
/* First you would have to add acf/save_post action to you function.php so the action runs every time a post is saved or udpated run before ACF saves the $_POST['fields'] data */
add_action('acf/save_post', 'my_acf_save_post', 1);
function my_acf_save_post( $post_id ){
	$fields = false;
	$catId = 27;
	/* Here I added a if statement so the code runs only for a defined category */
	if ( in_category( $catId, $post_id ) ) {
		// Check if Fields have been posted
		if ( isset( $_POST['fields'] ) ) {
			$fieldId = 'field_5343d06c3e9dc';
			$fields = $_POST['fields'];
			// Store the true/false field on a variable (change the "Field_xxx" id by yours)
			$featuredArticle = $fields[$fieldId];
			// Check if the true/false field is true
			if ( $featuredArticle ) {
				/* If it's set to true do a WP_query so you can get the other post that have $featuredArticle set to true here you may want to change the 'cat' to whatever your is (or to all) in the meta query you should use your true/false field name as a key */
				$args = array(
					'cat' => $catId,
					'meta_query' => array(
						array(
							'key' => 'featured_article',
							'value' => '1',
							'compare' => '=='
						)
					)
				);
				$post_query = new WP_Query( $args );
				/* Here we check if the query returns post (if it does it will return featured posts) */
				if ( $post_query->have_posts() ) {
					while ( $post_query->have_posts() ) {
						$post_query->the_post();
						/* For each posts we update the true/false field and set it to false */
						update_field( $fieldId, false, get_the_ID() );
					}
				}
			}
		}
	}
} // end my_acf_save_post

Ummm something doesn’t go well. Here is my code:

/* When a ACF "Featured article" (in 71% articles) is set to true, all the rest are updated to false */
/* First you would have to add acf/save_post action to you function.php so the action runs every time a post is saved or udpated run before ACF saves the $_POST['fields'] data */
add_action('acf/save_post', 'my_acf_save_post', 1);
function my_acf_save_post( $post_id ){
	$fields = false;
	$fieldId = 'field_5343d06c3e9dc';
	$catId = 27;
	/* Here I added a if statement so the code runs only for a defined category */
	if ( in_category( $catId, $post_id ) ) {
		// Check if Fields have been posted
		if ( isset( $_POST['fields'] ) ) {
			// Store the true/false field on a variable (change the "Field_xxx" id by yours)
			$featuredArticle = $fields[$fieldId];
			// Check if the true/false field is true
			if ( $featuredArticle ) {
				/* If it's set to true do a WP_query so you can get the other post that have $featuredArticle set to true here you may want to change the 'cat' to whatever your is (or to all) in the meta query you should use your true/false field name as a key */
				$args = array(
					'cat' => $catId,
					'meta_query' => array(
						array(
							'key' => 'featured_article',
							'value' => '1',
							'compare' => '=='
						)
					)
				);
				$post_query = new WP_Query( $args );
				/* Here we check if the query returns post (if it does it will return featured posts) */
				if ( $post_query->have_posts() ) {
					while ( $post_query->have_posts() ) {
						$post_query->the_post();
						/* For each posts we update the true/false field and set it to false */
						update_field( $fieldId, false, get_the_ID() );
					}
				}
			}
		}
	}
} // end my_acf_save_post
