It would be sucking under hood air, which is usually quite hot. It would also be mixed with the much greater volume of carb air before hitting the valves. I say no danger.
I had a wolf whistle on my 55 Chevy in high school, and never had a problem.
Once in a while I'd have to spray some light oil on the whistle spinner to make it blow.
Also make sure the whistle spinner isn't installed backwards. The spinning disc faces AWAY from the open end of the trumpet.
