Topic header editing question

Can I edit a topic header for a topic that the posted header is a link to YouTube? I would like to change this thread to a Microsoft Flight Simulator mega thread. Do I just make a new thread and merge this one in? What is the best practice?

Usually I have no problem editing the title, for some reason it is not showing the little edit pencil:

What I am trying to do is change the title of the aforementioned thread to “MS Flight Sim 2020 mega thread
