What are the rules regarding playing DCI sanctioned Block Constructed formats with cards from a core set such as M15? (I'm thinking of Innistrad-Avacyn Restored block).

None of the currently sanctioned Block Constructed formats include any core sets.

All players in a sanctioned Block Constructed tournament must be using the same block.

The list of currently available Block Constructed formats that can be sanctioned is in the Magic Tournament Rules, that you can find here:
