Yes, it is legal to connect the PCM to a 20 amp Breaker, and not the PCM connection on the PDP.
The Robot can have One and Only One compressor. R48 says "PCM - with compressor". If the compressor had to be connected to the PCM at the PCM connection, then it would be impossible to also have another PCM with a compressor connected to a different 20 amp circuit.
In addition, you are not required to use the PCM to control your compressor. You could use a Spike Relay as rsisk mentioned. Again, if you had to use the PCM, then there would be no reason for R66-D.
