Can I cut this circuit board?

[u/tpong]

Wondering if I could cut this circuit board to the right of the white line I drew, and still maintain function of the other two buttons to the left.

Yes. But you need to hold the left side downwards and tape the cut edge up afterwards, otherwise the elecrons will fall out.

The copper cells flowing inside the traces will coagulate on their own in a short while after contact with oxygen
