The X11R4 version of the protocol specification states the following in the
section on the CreateWindow request (it's on page 14 of my version):

  Output to a window is always clipped to the inside of the window, so
  that the border is never affected.

So the answer is no.  The server will always clip a child to the interior part
of its parent.  If you want window A to have more visible area than window B,
then window A must be something other than either a direct or indirect child of
window B.
