Yes. (In fact I presume the overlaid data is PD in this case so no problem.)

This is a funny example because you could conceivably cut out a corner
from the map, then place the image where it is now... it is just about
conceivable to make a copy of this map without copying the image so
maybe this could work as a collection.

Certainly the whole map needs to by CC-BY-SA.
We did have some pages with examples about this on our wiki, years ago.
I remember the example was a tourist guide with maps and photos, and
there were several cases where maps and photos (and text) were sometimes
superimposed, sometimes side-by-side, and the whole thing was commented
as to what is derived and what is collected. I cannot find it now, however.
I think that in those examples, there was the concept of interaction and
co-dependency - the question of "does the overlaid stuff work without
the map". So if you carefully place your photo or illustration at a
certain point in the map, and your photo or illustration would lose its
meaning without the map, then it is clearly a derived work; but if your
photo just sits there and could just as well sit there without the map,
then it could be called a collection. This is not an interpretation I
necessarily share and I'm not sure about the exact wording but it has
something going for it.

I don't think this interpretation is particularly strict. There have
indeed been several people requesting that my OSM book be fully
CC-BY-SA'ed because it contains OSM illustrations on some pages - *That*
I call a strict reading (and one I clearly don't share).
