It isn't a matter of the FCC allowing it or otherwise. It is a matter of Apple designing it to reflect FCC regulations. FCC regulations are there to prevent interference with services in the EM spectrum. This interference could cause problems with everything from emergency communications for fire and police (unlikely in this case) to your neighbours radio or TV.
This is why it is a bad idea to remove things like RF shielding and RF chokes from your equipment, even if it does make it look cooler.
