It depends on how, "off "it is. All the main runners are suspended on wires. You can only shift them so far without actually moving them.
You can try removing the 2' perimeter rails and all the tiles. Shift the main runners so it sets parallel to the walls and reinstall the ones that fit and cut new ones that do not.
You will need new tiles.
They will not match in color unless you replace them all or spray paint them.
