Oh yes, absolutely if that is your intention. I thought you were wanting to experiment with the PCB itself.

Before you take a cart apart, pull back the card edge cover at the bottom of the cart and hold it to a strong light, then peek on the inside top of the motherboard. If you see a tiny black blob, you know it's not the cartridge board with the PROM, so it's probably best to leave it be.
