Yes Yes Yes. I hate lead-free "Sorry California" solder. Products manufactured/sold in California must not contain lead. As a result, most elements are now much more difficult to desolder, even with temperature controlled equipment. Thinning the joint with it will solve the problem. Now you can remove the old component with a wick, hand solder or vacuum solder without damaging the board. Then re-solder with lead-tin solder so you don't have to use it next time.
