I doubt it. Any electronic device manufactured in the US has to pass FCC interference standards. The bulb has limits on how much interference it can produce and your opener has limits on how much it has to accept. I'd be quite surprised to find out this bulb caused issues, but without an analysis that would cost far more than either the bulb or your opener, the only way to find out is to try it. Guess what? If it interferes take it back.
