I don't know what you are talking about. Many licenses don't mention trademark issues at all, that doesn't mean they grant you the right to use the trademark.
"Not mentioned at all" does not mean you can do it. Licenses do not restrict, they permit, from a default of "you may not use my stuff".
The license text could also say "you may not break into my house". That would not make it a "narrowing of rights", and that doesn't mean other licenses implicitly grant you the right to break into the software author's house if you use their software.
