LCA H1 Amendment needed for Work From Home ?

I got my H1 approval for client Company A based in City X, the LCA also shows city X as place of work. Now, the same company is ready to give me the option to Work From Home from City Y which is 900 miles from the location mentioned in the LCA. If i take this offer do i need to have a new LCA and also an H1 amendment. My client company, position, roles and responsibilty, H1 employer will all remain the same.
