> The name Go is not trademarked by Google, at least as a programming language trademark. There are other things Google makes called Go (an interesting signal on its own) and they might be trademarked, but Go the language is not a trademark.
I'm not confident I'm correct only because it seems unlikely Google would have a page listing trademarks it doesn't actually own. That being said, I'm pretty sure there's no other place to search for trademarks.
I also don't think there is actually a trademark on the term "Go" based on this USPTO search: http://tmsearch.uspto.gov/bin/showfield?f=toc&state=4809%3Ax.... But admittedly I've only looked through five or six pages; using the option to search for an exact term doesn't seem to cut down the search results at all.

Putting a ™ symbol after a name is only a claim on that name to be one's own property for use as a mark on some product or service when trading, and big corporates do this all the time. So I think it's likely Google would have such a page.

There's a distinction between a trademark and a registered trademark. Registering the name in some jurisdiction's database just means the corp has begun its defense of that claim before it sees a perceived infringement.
I would imagine everyday words like "Go" (or "Groovy") wouldn't be accepted by the US trademark office anyway, so perhaps Google tried but failed to register it there. They might get "Golang" accepted but the Go team have said the name of the language is "Go" not "Golang".
