Laptop Coppermine Celerons Into Desktops

There are two coppermine celerons, the SL54P and the SL4TF (800/100),
that are frequently used in laptop units and I was wondering if they
could be installed in desktops. Their sspec info looks similiar to
others, with exception of wattage being lower 20W vs 24W or so.
