One of the great advantages of LEDs is that they generate very little heat - hence their ability to generate more lumens per watt than an incandescent bulb.
Given the absence of heat, I'm not sure by what mechanism they would damage the lens.

LEDs can still produce a massive amount of heat.
I have a Nitecore torch that gets too hot to hold the head after less than a minute. Like many it has a laser engraving warning it may be hot. They do tell you about the fire risk - imagine that being left on in a packed bag, and provide lock out functions etc.
I did casually put it against an old pair of jeans and got smoke within seconds. Of course, the LED in a torch is confined in a small area and the beam is tightly focused.
There are many LED headlight ‘bulbs’ with fans to counter the heat they produce. Some do away with the fans and use passive cooling - fins cut in the aluminium base. Philips have done a version that has passive cooling and fits in a standard housing with the rubber backing in place. It’s not their brightest (as good as a normal halogen) but it’s a big step forward for fitment.
I’d say it’s possible. Depends on your LED, if the fan is still working (if it had one) and how the base conducts heat through the reflector hole.
