No, it's not a direct swap. The S5 pump is electric, and the S5 ECU needs to see a signal from it to avoid going into limp mode (extremely limited performance).
To use an S4 MOP, you would need to swap the front cover of the engine for an S4 one. Then you would need to swap out the ECU, wiring and sensors for S4 versions to avoid limp mode (or a full standalone ECU).
If your S5 MOP has failed (common), you will need to replace it with a working one or get your ECU chipped by Pocketlogger: Rtek7 ECU Upgrade Detailed Information. If you go this route, you must premix 2-stroke oil into your gas.
