PCV vs UG-126(b)

No.
The exception would be in certain services if such a setup is designed so it was at least as reliable as a pressure relief valve. An instrumented control system that replaces a PSV typically has to be SIL 2 or higher.

UG-126(b) refers to pilot actuated relief valve, not a pressure control valve. PCV, as per my knowledge, cannot replace relief valve under any circumstances.
