I'd recommend using (kbd "C-=") instead of [(ctrl =)].  It looks clearer
because it uses the format emacs uses for printing keybindings, too.
But that doesn't have anything to do with your problem, both forms are
equivalent.

Yes, various bindings are not available inside terminals.  It's a
terminal limitation, not an emacs one.

Generally speaking, all keys like C-X where X is a alphabetical or
numerical letter should work in both cases.
