Very doubtful. What I would do in your situation is get the strongest screwdriver you have that fits the screw head, and get a hammer. WEAR GLOVES. While turning the screwdriver (and NOT stripping the screw), whack the handle end of the screwdriver with the hammer. This is essentially an "impact driver". It helps to break the rust bonds, as well as keep the screwdriver in the screw head and prevent it from slipping out and stripping (which is what would happen if you used the cordless drill).
I've done this before and it works just fine, although now that I found an impact driver on sale at Canadian Tire I won't have to bother with that method any more.
Edit: You can also substitute a piece of 2x4 board, or anything heavy with a flat surface so whack the screwdriver handle with (dead-on... driving the screwdriver INTO the screw). A hammer can be tricky when you're trying to twist the screwdriver and you might end up missing the handle -- OUCH!
