The picture below clearly shows that it is possible. The Z61t in question is the one I had recently acquired from GnatGoSplat, with a C2D CPU. This is one of the late Z61t models, which according to the Tabook can output DVI, as opposed to the earlier Core Duo-based models, which apparently could not.
Shown here outputting both to a VGA and a DVI monitor, via the Advanced Mini Dock.
This is the exact model of the Z61t:

I also have a T60 with GMA950, which can also achieve the above through the same mini-dock:
