That would be nice.
The manual for the TC-16A isn't very useful. It only
lists a couple of lenses. I guess it dates from way
back in the dark ages when there were only a few AF
lenses.
The reason it gives for not using the TC-16A with
some lenses is that it could damage the teleconverter.
Looking at the lenses that I own which are specifically
listed as NOT compatible, what they seem to have in
common a rear element that protrudes past the lens
mount. Maybe somebody else here knows the reason
for certain.

It works fine with the AF 180mm/f2.8N. I don't think
that the 'D' differs from the 'N' except for the upgraded
electronics.
When I bought the teleconverter, I spent a couple of
minutes playing with the store's 300mm/f4 on it. It
auto-focused well, and the image looked great through
the viewfinder, but I didn't shoot any film with it.
Image quality with my old 300/4.5 (non-ED, non-IF) is
decent, so I suspect that with the dramatically better
optics of the newer 300, the combination would be
excellent.
