Is an amp that fails at one minute with 100w FM
better matched than an amp that fails at two minutes
with 100w CW?

No, you've got the concept backwards. Obviously the worst matched is the
1 o=minute case, next would be the 2 minute case and so on up to one which
runs for about its MTBF at the connected load. This last case would
likely be the one the designer was targeting.
