No. AMD Athlon XP's use a different socket type (Socket A (462)) while the Pentium 4 uses socket 478.

There hasn't been a standard CPU socket design since before the Pentium II. Intel moved to the Slot 1 while AMD made gradual improvements to socket 7. Then AMD tried their own Slot A design. Eventually both abandoned the Slot idea and went back to sockets but there hasn't a cross compatible socket design since 1994.

You can't put the P4 into the AMD's motherboard, no. But you might be able to migrate the P4+motherboard (and maybe +RAM as well) from the Dell case into the Compaq. If you end up considering that, also consider that it might be simpler to migrate the components from the Compaq into the Dell's case.
