People can certainly be compelled to do things they would not otherwise do by what people would ordinarily call hypnosis. The focus on harm brings MK ULTRA to mind. However, a more generic definition is widely documented in the medical literature, see e.g.
The Prefrontal Cortex and Suggestion: Hypnosis vs. Placebo Effects. <http://journal.frontiersin.org/article/10.3389/fpsyg.2016.00...
Self-harm may not be possible, as you say. Given the the nature of hypnotic suggestion, I speculate it is possible to suggest a separation of the physical self from the harm, and in that way trick someone into self harm. Particularly when combined with mind-altering drugs like LSD. But I've no evidence other than the reports linked.
The MK ULTRA report was read into evidence at Senate hearings because the truth of the report indicated abominable and deplorable practices. Nobody has, in spite of powerful incentives to do so, denied the truth of these reports. That ought to be a compelling indicator, IMHO.
Though I did not see an article discussing harm, dozens of articles on PubMed describe the effects of hypnosis (versus placebo).
I feel like your standard may be practically unattainable, meaning one must ask: What sort of evidence would convince you?
