With vinyl floor tiles the movement isn't a problem as they're flexible. I do usually replace the floorboards with some kind of sheet material unless it really won't make any difference, like a small floor with very little movement in it. I'm not sure the adhesive allows for much movement but it's fine as long as the tile flexes.
