They're not the same thing. Fatigue is where a small crack propagates 
through the material, possibly to the point where it breaks. For a reed
that would mean the brass is effectively more flexible so the natural
frequency would drop. Work hardening doesn't involve breaking of the
material, it's an effect on the crystal structure rather than on the
overall geometry.
