I do not know, that is why I suggested contacting the manufacturer directly. I would consider rolled vinyl to be more of an underlayment as it tends to be on the softer side. The potential concern is that some floorings cannot have an underlayment if you place a heavy load on the flooring the underlayment collapses and you get cracking on the new flooring at worst, or a dimple at best.
