Macs and PCs can share RAM as long as it is the same spec. In this case, spec includes form factor, speed, error-correction, and some aspects of organization.
Some motherboards (yours is probably one of them) require SIMMs to be in identical pairs, but not so DIMMs. Some motherboards require dip switches to be set or BIOS changed to reflect changes in RAM.

Good luck.
