Ionut Staicu posted a solution to this here, not for a true/false field but it can be adapted to that, at least the JS side of it http://support.advancedcustomfields.com/forums/topic/custom-location-rules-js-part/
I created the rest of the code and for the location rules here https://github.com/Hube2/acf-custom-field-locations-rule, using this has some issues that I outlined in the readme. You are welcome to use it as an example for a single field. Take a look at the documentation for custom location rules here http://www.advancedcustomfields.com/resources/custom-location-rules/
