Yes. But they'd choke each other to death before it happened.

I wasn't joking, actually! Mint has a very aggressive root system, and it's hard enough keeping the roots from crushing themselves with one plant in a pot, let alone two! Crush/choke/squash/squeeze the roots of a plant and it can't eat or drink. Like you trying to drink through a bent/crushed straw.
