Depends. It is wide enough but it depends on the base on the TV. My 43" has legs just a few inches from the sides of TV instead of a center base. It only left an inch to the edge of the stand. Would work, but precarious.
And it is obviously a corner unit. This should fit if you're not dealing with a lot of cables in the back. If so, the depth could be just a little over 19" with cables.
