Yes, if the target chip has had it's fuse settings change in the past to work with an external clock source that would prevent it from working.Lefty
I don't have any 16 MHz oscillator. Will I have any problems by using a different frequency (14 or 22)?
Not for just the purpose to burn a sketch or a bootloader onto the target. However the frequency does need to be correct for the bootloader to work with the arduino IDE as the baud rate will not be correct if not clocked at the speed the specific bootloader was created to work at.
