Apparently, if there's any, it is over a megabyte (!!).
That's pretty big, but variable names are meant for your compiler. The compiler translates variable names into addresses, and that address will be 2 or 4 bytes. The compiler runs on your PC where there is plenty of memory, and your Arduino just deals with the address.
Since the compiler runs on your PC, the name length doesn't depend on the Arduino model.
