Is there anything that would point to this possibly being the case?

Maybe it's part of the Epstein files, he was famously wearing US Coast Guard shirts ;)

If it also contains a sensor network to detect adversary ships and submarines, it would be bad if someone else can use it to track US submarines. Or the sensors are too old and their resolution can't detect modern mini submarines or autonomous drone ships such as the ones the Ukraine is using in the black sea, so they need to be upgraded.

These people are PR professionals and have been doing propaganda since generations. If Trump speaks about Greenland he does not mean the country but he uses it to bury another Greenland entity that he does not want to be associated with. Same with Canada the country vs. Cañada the Spanish word. Bonus is if they can ragebait their political opponents because then nobody will ever again be able to find the original story with these keywords.

And to me this kind of story and easy anti-climate-change narrative checks all the boxes.
