No it can't, the motherboard is what determines how much Ram your system can take.
So is it possible to upgrade the motherboard and increase it?
Doubtful. You'd have to find a slightly different version of the exact same laptop (that allows more RAM) for that to be possible.
All the pieces in a laptop are designed around each other. Case, motherboard, cooling, ports, connections, screw holes...all working together. You can't just swap in another one.
Upgradability is one of the tradeoffs for weight and portability.
