Why not? Over here, everybody I've dived with tucks their seal, whether it's neoprene, latex or silicone.
When I had a neo suit with neo seals, I tucked the neck seal. If I didn't tuck it quite right, I got a cold shower down my back if I turned my head too much. Now I have silicone seals, I still tuck my neckseal. No more issues than with a neo seal, except it's a little easier to get a fold in the seal where water can seep in. My son has latex seals, he tucks his neck seal and it works great for him. Just make sure there's no vertical fold, and everything is A-OK. And make sure there's one tuck, no rolling, and that the seal is tucked about halfway up.
One advantage with tucking the neck seal is that if there's less risk of the seal "burping" air since air pressure against a tucked seal will go into the tuck and increase the sealing against your skin, while a flush seal will burp if you get a bit of air pressure against it. Underwater, a neck seal burp will probably give you a cold shower down the back, and on the surface the suit holds less air if you're not quite horizontal in the water.
I've done north of a hundres drysuit dives, in water down to 3-4 degrees C (37-40F). Most of them below 10 degrees C (50F). And some of those who I dive with probably have north of a thousand drysuit dives in our waters. They tuck, too.
