Can I Grow Rose of Sharons From Cuttings?
How and when can I cut the stems of my Rose of Sharon to grow more plants?

I would say yes. Since Rose of Sharon shrubs are actually a variety of hardy hibiscus, cutting would be taken much the same way. They also self-seed when not deadheaded, so you just might find some seedling growing beneath the shrub, which you can easily pull and pot up or transplant elsewhere.
