Is It Against Google’s Terms of Service To Include Links In A GMB Post?

In episode 197 of our weekly Hump Day Hangouts, one participant asked if it's against Google's Terms of Service when you put links in a GMB post.
The exact question was:
Hey Guys
Recently I was told by someone that, when you put links inside your post (GMB), that it is against Googles TOS. Is this true? I haven't been able to find it in the TOS.
If it is true, Why would Google make those links inside your post clickable, (live links)?
