Both GFDL and CC-BY prohibit derivative works from removing "copyright notices" appearing in the original. The licenses are ambiguous about whether one can validly relocate such notices that are embedded in the image to the description page.
Standing practice on Commons is to remove watermarks when possible, but also to allow the uploader a free hand to request deletion of the image if they object to that removal.
