That's like arguing a condom is less effective at preventing pregnancy than a trash bag, because the condom isn't as big.
No, not really... the suspension trauma happens because the harness straps squeeze your arteries shut, blocking the bloodflow and causing stagnation. If the harness has fewer and/or thinner support straps then you will have the same body weight spread across fewer/smaller points, increasing the pressure and making the problem worse. Blood becomes hypoxic really quickly if it can't move.
