Yes and it has nothing to do with what you're talking about. The modulus (stiffness) of steel (or anything that I know about) does not change because of work hardening.
People ride steel bikes with 100,000 miles on them. If fatigue was going affect stiffness, it'd be set in by then. Now if a steel bike is made from very thin walled tubing, it may be prone to fatigue failure (the same as aluminum), but that's a different thing entirely.
