Hello Jimmy,
Thank you for your prompt response, yes you can still use your license for your Project 2021 however I would like to set proper expectations that since this license is an MSDN license, you may not receive proper support in terms of the help and how to's. So long as you still have the license, you won't have any issues with activation as well so just keep the product key safe and you should be good to go.
Best Regards,
JK
