Can we use shim under positive displacement pumps?

Yes.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Usually we prefer to shim under the motor.

Depends on the baseplate / boltdown location - are the mounting pads machined and level etc, a poorly designed base might require some shim to ensure the pump case is not stressed or twisted.

Normal issue is that the pump is fixed in place by the piping connections so you don't want to start stressing that bit out to fix the coupling misalignment.
