It may work. You'd have to check the specs of the motherboard. I have a Tekram EX motherboard that will support a voltage as low as 1.3V, so theoretically, I should be able to use the Cel2's with a new slocket. Haven't had the chance to find out yet. The only reason you would want to do this with an LX or EX board is if you know the Cel2 won't do the dance at 100MHz FSB.
