I don't think so. When the pandemic hit, the fed made the reserve ratio 0% for all accounts, so counting savings accounts as M1 wouldn't really change how much money banks could lend. However, even under normal circumstances (transactional accounts have a reserve ratio of 10%, other accounts have a reserve ratio of 0%) counting savings accounts as transactional (M1) would actually increase the reserve requirement for banks, decreasing the amount they could loan and therefore decreasing M2 overall.
