Psychology Licensure Boards generally have jurisdiction over most aspects of the practice of psychology within the jurisdiction, rather than just the licensure of psychologists. This involves hearing complaints and assigning penalties to those who may be practicing psychology without a license. The legality of your plan is based on the jurisdiction(s) in which you practice. If you go the non-licensed life-coach route, there will likely be limitation not only on what you can do as a life-coach. Obviously, anything defined in the regulations as "the practice of psychology" will be off-limits, as will any other practices overseen by a licensure board (such as social work, marriage and family therapy, medicine, plumbing, etc.). Additionally, there will likely be limits not only on how you refer to yourself and your practice (i.e. you probably can't use the terms "psychologist" or "psychology" in any of your public representations of yourself or your work), as well as potential limits on how you reference your training and degree, such as referencing degrees or designations (e.g. "doctor") associated with your psychological training. If you decide to go this route, I'd suggest that you carefully review not only the licensure laws in your jurisdiction, but also any and all board memos, findings, sanctions, and other publications related to the practice of psychology, with special attention to any publications related to the "practice of psychology without a license." Opinions don't matter here- boards tend not to mess around with this kind of thing, and many regulations and findings have been promulgated to prevent people from doing exactly what you are suggesting that you might do.
