Yes, I just did that to a donated bike at the charity shop where I volunteer. Somehow, the non-drive side crank arm got bent such that it no longer cleared the chain stay. I removed the pedal and crank arm, clamped the crank arm in a bench-mounted vise, and slipped a long steel pipe over the arm, using the increased leverage to pull the arm straight again. Worked fine.
