Yes, I think so.  Command parameter change notification is emitted 
whenever command parameter is changed, it has nothing to do with other 
factors.

The session below is about what you want, IIUC,

(gdb)
set trace-stop-notes foo
&"set trace-stop-notes foo\n"
=cmd-param-changed,param="trace-stop-notes",value="foo"
^done 
 

(gdb) 
 

tstart
&"tstart\n"
=tracepoint-downloaded,id="1",address="0x080483ca"\n
^done
(gdb)
set trace-stop-notes bar
&"set trace-stop-notes bar\n"
=cmd-param-changed,param="trace-stop-notes",value="bar"
^done
