Yes! I'm on Atkins, and one of my favorite snacks is blueberries or strawberries with cream poured on top!
Or I'll make a protein shake, and throw in some berries for flavor!
Sometimes my mid-afternoon snack is an apple with peanut butter! (The real kind, not the kind with added sugar).
But, if you start a low-carb program, remember you can't have fruit during the first 2 weeks, because you're cleaning your system of all the sugars. If you can make it through the first 2 weeks, then you can slowly add some fruit to your diet!
Good luck!
