No, not while he is present: it is agreed upon from Abū Hurayrah that the Prophet ﷺ said a woman must not fast a day other than Ramadan while her husband is present except with his permission. The reason is his right over her, so if he permits, or is travelling or absent, she fasts freely; and a husband is not praised for blocking her worship without need. This restriction applies only to voluntary fasts — Ramadan itself needs no one's permission, and neither does a make-up fast when little time remains before the next Ramadan, though scholars say permission should be sought for make-up fasts while there is still ample time, since they may be postponed.
