You are not allowed to kill people with a machine gun, either.   ;-)
Restrictions that don't come from the licenses are, IMHO, irrelevant
when evaluating the compatibility of two licenses.

As a consequence, if you want to know if GPLv2+restrictions is
compatible with GPLv2, you should evaluate whether you can create a work
D which is a derivative of a work A (under the first license) and of a
work B (under the second license), while complying with both licenses.

These two licenses are not compatible with each other, because GPLv2
insists that D be licensed as a whole under the same terms of the GPLv2
(see clause 2b). This is not possible because the parts of D that comes
from A are not available under the terms of the GPLv2, but instead under
more restrictive ones.
