Sure, but there's way more distance between Ctrl and PgUp then Ctrl+Tab (I'm taking a classic desktop keyboard in the account now). There are quite some more compact models where PgUp/Down are between the NumLock and - on the right side with the Numpad.
Not to mention you'd need to set the hand from one end of the keyboard to the middle, just to press something you'd otherwise move 1 key.

As I said, it's dumb.
