Is this wall and the floor underneath it helping hold up the attic floor? Maybe it was put there to hide a problem?
If there is no gap between the top of this wall's framing and the underside of the attic floor I'd be careful. A non-load-bearing partition should be a sliding fit vertically, not an interference fit.
