Can I wear a tampon overnight?

My flow slows down a lot when I sleep. It's only when I move does it leak! I hhaatttee pads and I havent worn one in my life! I was think that since I go to bed at like 11:30 that I could put it in then, but I usually don't wake up till like 10 the next day, now that's its summer break! So maybe I could set my alarm for about 5 in the morning and change it. It doesn't bother me to wake up. I fall asleep easy anyways. Usually I only need to wear a tampon about 2 nights because then my flow starts to get so light that when I sleep it doesn't leak or anything! So can I wear a tampon? Thanks!!
