I have a 650C tub that came with one of my frames, and it's hub is drilled for 40 spokes, but it's only laced up to a 20h rim.
It might just be that the 20 holes that aren't used are just there for show of course, but you could build it into a completely lethal & totally not recommended under any circumstances whatsoever 20 spoke wheel.
