Not really, no. I can send TSTP and CONT to processes. See Why did my trap not trigger?

That's a slightly different issue: you can send signals from another terminal, and they will get deferred until the system sees fit to pass them to the process. My point is that Bash Ctrl-Z itself stops the process indefinitely: a stopped process cannot receive any signals. It cannot even be killed by SIGTERM until it is also restarted by Bash job control. It cannot be resumed by Ctrl-Q, but (special case) it can be resumed by SIGCONT.
