Yes they do, to aid in swimming, walking, and defense.
Tortoises move by using all four legs to walk on land. They have a slow and steady gait with legs that are adapted for walking on land rather than swimming. Tortoises are not agile creatures and may take their time to navigate their environment.

When a predator tries to eat them, they withdraw their legs, tail, and head into their shell. While hiking, I have found desert tortoises that had been turned upside down and left for dead. I always turn them right-side up again.
The main difference is that snails are mollusks with shells, while tortoises are reptiles with shells. Snails have soft bodies and move by sliding on a single muscular foot, whereas tortoises have hard shells and crawl using their legs. Snails are usually aquatic or terrestrial, while tortoises are exclusively terrestrial.
Terrestrial and arboreal reptiles like tortoises and lizards use their legs to crawl around. Aquatic turtles use their legs to swim and crocodilians use their tails and legs to propel themselves. Snakes use their backbones and muscles to swim, slither and burrow.
