OS X installers have always been fairly specific, hardware-wise. I haven't read anything reflecting that situation with the Recovery HD, so it may be that the Recovery HD created for the MacBook Pro does not have the necessary drivers for the Mac Pro. Obviously, nothing definitive here, but a possibility.
