As long as you have an approved 140, I think you can re-link your PD to your new petition.

If you have not submitted 485, you have to start from the beginning to apply for the green card if you change your job now. However, you can re-link the PD. If you have a 485 pending for over 180 days, you are safe, and no need to re-apply.
