Quick question bout haloreach/cea

my question is if i let my friend borrow halo reach is there a way i can play with him with my halo cea disc?
so are any halo reach maps on the cea disc??

With CEA comes a code to download the Anniversary Multiplayer Maps to Reach as a DLC add-on, if you install those maps and you give your friend CEA, you can play on the 7 Classic Maps with him.

Nothing else.
