It depends on whether you assume that there's a separate license by that
name. In practice, it's a placeholder for the licenses it's available under:

"The Open Source Edition is freely available for the development of Open
 Source software governed by the GNU General Public License versions 2 and 3
 (?GPL?). The Qt Commercial Editions must be used for proprietary,
 commercial development."

However, quickly skimming that page, I can see how you could reach the
following conclusion:

No, the Qt Open Source Edition is GPL version 2 or version 3 (your choice)
with exceptions (additional permissions) that let you link things to it that
you couldn't if it was pure GPL. It it was GPL + restrictions, it wouldn't
be GPL compatible (you can't add restrictions to the GPL, as I understand
it).
