Not true, old boy. I have flown a civil Airbus A330 on numerous occasions with a casevac fit. It took three rows of outboard seats to accommodate the stretcher and harness. There was a large oxygen bottle to hand, plus a doctor and nurse with all the requisite kit in adjacent seats. Of course, it was all paid for by the patient's insurance company. All very similar to what I recall seeing as a passenger on a RAF VC10 flying from RAF Muharraq to RAF Carterton East many years ago.
