No not really. With the Instrument track the MIDI and audio are tightly integrated. But a rack Track just uses a midi channel as an input. And you could if you wanted send 20, 30 or more MIDI Tracks to the same Rack Instrument (why 
but you can). In that case you wouldn’t want changing the name of one of many MIDI Track also change the name of the Audio Channel in the mixer. The same behavior also also happens if you use the relatively new capability of routing multiple MIDI Tracks to an Instrument Track. In that case changing the MIDI Track name does not change the name of the Audio Channel it is playing on in the mixer - although changing the name of the instrument Track will because of its tight audio/midi integration.
