Without knowing which HSF you were using on the celeron it's hard to
make a definitive answer as you may have had one terrifically over
rated for the job but the odds are, no. The Celeron 500's thermal
dissipation is about 27 watts while the XP 2100+'s thermal power
rating is 62 watts (both full load). You'd be asking it to cool a
processor that generates well over twice the thermal power it was
originally handling.
Plus, to answer your 'special requirements' question, yes, beyond the
thermal power matter the Celeron has a metal heat spreader whereas the
athlon has an exposed die. The problem here is that it's fairly easy
to get a heatsink to sit on the rather large metal can but the spring
clip needs better alignment to ensure a proper fit on the small Athlon
die (else it tends to 'tip', rubber bumpers notwithstanding). And
Athlon HSF assemblies have stronger spring clips. It's unlikely that a
HFS assembly designed for a Celeron would sit properly on the Athlon
and, if it didn't, you'd have a dead processor in about 3 seconds
after power up.
The cost saved by trying to reuse an old HSF designed for a different
processor just isn't worth the risk.
