32GB of memory in Kaby Lake laptops

Hi! I would like to know whether it is possible to put 32GB of memory (as 2 x 16GB DDR4 SODIMMs) into the Kaby Lake version of the ENVY 15 (specifically, the as104na: http://store.hp.com/UKStore/Merch/Product.aspx?id=ECC_BUNDLE_6156376 ). The documentation suggests that 16GB (as 2 x 8GB SODIMMs) is the maximum, but it's unclear whether this is actually accurate or has just been copied from previous-generation documentation - otherwise-inferior competing products using the same processor and chipset such as http://www.dell.com/uk/p/inspiron-15-7560-laptop/pd?oc=cn75602&model_id=inspiron-15-7560-laptop clearly advertise support for 32GB of memory as 2 x 16GB SODIMMs. I can see that there are similar answers around for previous generations of the product, such as http://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Is-32GB-RAM-possible-in-an-HP-E... , but does this answer continue to be true on the new versions? If so, can you offer some explanation as to where this restriction comes from? (For example, if it is really a testing/certification issue rather than some sort of hardware deficiency and therefore actually will likely work (without being explicitly supported) then I would be happy to take my chances with that setup.)

32GB is not tested and may cause unexpected results.

HP ENVY Notebook PC (model numbers 15-as100 through 15-as199) support 16GB Maximum.

Two memory slots, non- accessibl. Which means that RAM is not upgradable.

Support for DDR4-2133 Dual Channel Support for up to 16-GB maximum on-board system memory
16384 MB (8192 MB × 2)

Can you clarify whether the RAM is upgradable or not?  These two points seem directly contradictory, since the service manual appears to describe the procedure for upgrading.

 

Assuming that upgrade is possible:

Do "unexpected results" imply that it can't possibly work, or just that it may work but isn't tested and HP does not wish to support it?  Also it would be helpful if you could offer some explanation as to why,  given that the linked product above from another manufacturer with apparently-identical setup does support it.
