Yes.  It seems like we can probably get geo coordinates for these, but so far I haven't found linked-data identifiers.  I could check other geographical name databases, but I'm not sure any of the others are available as linked data.

Alice, if we can't find a URI for these places, do you think it's still useful to embed the coordinates?  And if so, could you point us to documentation or an example of how you'd like it tagged?
