I would suspect that the limit of 150 kg is nothing to do with the GVW or permitted axle weights but rather what the van's structure can accept. Also as I'm sure you are aware, 150 kg loaded behind the rear axle adds more than that to the load on that axle but as I say I suspect that the 150 kg is more to do with the van's floor and / or sub-structure.
