Sure. Some memoirs state this in the foreword. There are also memoirs that are "fictionalized", like James Frey's book "A Million Little Pieces." Originally published as a memoir in 2003, it was later revealed that many of the events Frey described were exaggerated or fabricated. This caused a lot of controversy at the time, but many subsequent memoirs followed this pattern and I think it's become quite accepted in the genre.
