No. See section 0. <http://www.gnu.org/licenses/gpl.html>
    To “modify” a work means to copy from or adapt all or part of the
    work in a fashion requiring copyright permission, other than the
    making of an exact copy. The resulting work is called a “modified
    version” of the earlier work or a work “based on” the earlier work.

As a copyright license, the GPL could not possibly demand that it be
accepted in order to do something for which no permission is required,
and here it explicitly disclaims any such demands.
