I'm fairly confident that if it's off it's not on the network, so it cannot be turned on remotely either. (Baseband hacking and fake-off malware aside. That would be very easily detected, because batteries would die left and right.) Sure, it's not 100.0% off, for example the battery management system is consuming some power, and maybe it's motherboard is "energized" like with ATX boards, so it can respond to switch on via keypress (which worked on PS/2, and probably there's some USB functionality that can do this too).
