You should be able to. You will probably have to exit out of the calibration setup. but I don’t expect that is much of a big deal.

Also, after reading some of the other comments here, I would suggest looking closely where the Bowden tube enters the hotend. (see arrow in the linked picture) There is a fitting right there that will allow you to remove the tube. Push the black ring down and gently pull up on the tube. It should pull right out. Then it’s a simple matter of, heating up the hotend, grab the broken filament with your fingers or a pair of pliers, and perform your filament removal step. Replace the tube once the filament has been removed.

Can you manually heat up that hotend and then advance the feed while pushing in some new filament by hand? If you use a different color, you will be able to tell when the old color has been purged.
