No, you cannot apply for visa to Vietnam when your passport expired. In such this case, you are advised to renew your passport before applying for Vietnam visa because it must be valid for at least 6 months.
The processing time to renew a passport may take 7-10 working days depending on your Embassy so if you wish to travel to Vietnam on a certain day, please check carefully the expiration date of your passport.
