In brief: Yes

For most people, after around 7 years as a nonsmoker, the lungs do heal.

In brief: Yes

Yes, it is possible for your lungs to heal to a certain extent provided one stops eary enough before severe permanent damage/scarring or disease has set in.
By definition, one has COPD if one has smoked a pack daily of cigarettes for 20 years or more. Statistically, if one stops early enough one's risk of getting lung cancer decreases to non smoker levels if one quits for 5 years or more!
