My sister's Kenmore Dryer MN 110.76902690 makes a buzzing noise (much
like an electric buzzer) when I press the start button.

There is a decal on the door that says the dryer will make a noise
(unspecified) if you try to start it and the lint trap is full. The lint
trap isn't full, but, looking into the cavity it goes in, there is a lot
of lint that has escaped past the lint trap over the years. I tried to
get it out and could only get some of it.

The dryer won't start, noise is there.

Is it likely that even with the trap clean, there is enough lint in the
ductway that the sensor is showing a full filter? Can I clean this part
of the duct easily?

The noise is a buzzing, and I wouldn't consider it a stuck motor noise,
but could this be it?

Any other suggestions, things to check?

If you try turning the drum by hand while pushing the start button, will the motor keep it going? If so, probably a solenoid. If lint is the problem you may need to clean the whole exhaust area. Dryers collect lots of lint. Repairclinic.com has a generic video showing how to disassemble a dryer--the top comes off, then the front.
