I would not concentrate on the "guyed" part in the definitions, it depends
whose definition you use, and it isn't so relevant (IMHO).

a tower may not have an "internal" space (in the sense of closed space).

They can be slim. Especially "cooling towers" are a different beast than
most of the other towers, and I would not tag them as a subtype of tower,
but rather with their own tag man_made=cooling_tower (which btw. is also
done for a long time, although it is not the only option, currently).

there is no definition that requires being habitable for a building.

+1, it basically says nothing more than more than one usage. Looking
closely, many/most towers might be seen as "multi purpose" (radio AND tv?),
it would rather reduce usefulness of our data than improve it.
