Technically, the Game Boy's CPU is slightly different from the Z80, but
extremely close. But I'm nitpicking.
That said, there has been at least one Game Boy emulator written in C
for the TI-89, TI-92+, and Voyage 200 calculators, which use a totally
different Motorola 68000 processor. If a ~12 MHz 68000 can do Game Boy
emulation, I don't see why an even faster ARM processor couldn't also do
it.
The CPU is only half of the problem. Even on the Z80 TIs, emulating the
Game Boy's hardware is no trivial task, and is probably even more
challenging than emulating the CPU itself.
