I actually asked about this point when IBM came out with the RT machine.
The answer was:  "The official IBM definition of RISC is 'Any IBM machine
with fewer instructions than a System/360'".

This comes about because all IBM RISC work began with the 809, an attempt
to strip down the S/360 instruction set.
