Yes, you can correct a typographical error in an inventor’s name after a patent has issued. However, this requires a different process than correcting inventorship. As stated in MPEP 1481.02:

“Where applicant’s typographical error in an inventor’s name is recognized after the patent issues, a certificate of correction under 37 CFR 1.323, the fee set forth in 37 CFR 1.20(a), a petition under 37 CFR 1.182, and the petition fee set forth in 37 CFR 1.17(f) must be filed to request correction of the typographical error in the inventor’s name.“

This process is different from inventorship correction and is specifically for typographical errors in names.
