What sort of 'evidence' are you wanting? Isn't the fact that situations like this one in the UAE could be avoided evidence enough? And no, "league" isn't the problem, "rugby" is. The official name of the sport is Rugby League Football, we should consider using the shortened version "League Football" rather than "Rugby League".
before you rebrand a sport with clubs competing in it that date back to 1865 just in order to satisfy virginal UAE union administrators and the terminally short of attention you'd better be sure that a change will pay off many times over. You are after all throwing RL heritage right out of the window undoubtably to the benefit of our competitors. And considering it never held Australia back, a country most notable for castrating the machinations of RU in the 1920's rather than pandering to them I would say keep "Rugby" , be better at informing the audience and decry the detractors.
