@Barbara2543 Absolutely yes, If you specify an amenity on your listing, and then remove it without letting the guests know it can be a real issue… and a violation as far as Airbnb are concerned. I would advise that you contact anyone booked, let them know about the Treadmill not being there anymore and give them the option of either a discount for the missing amenity, or a penalty free cancellation in order to mitigate any issues with complaints.
