I've never had any big issues using older RoHS pcb's. I think all that happens is that the solder pads corrode slightly, and it takes a bit longer for the solder to flow freely, but if you're careful and diligent you'll still be able to use them.
I certainly have a big enough stack of them here - I keep them stored in individual sealed plastic bags, which helps supposedly.
