Nope.
It has 4 DIMM slots, so only 4 sticks of RAM can be installed at once. Also, for dual channel mode to work (which improves memory bandwidth), you have to have matching amounts of memory in corresponding slots.
There will either be two 2 GB sticks and two 1 GB sticks (only way dual channel will work), three 2 GB sticks (most likely, since manufacturers tend to ignore dual channel memory completely), or a 4 GB stick and a 2 GB stick. To install 16 GB, you'd have to remove all of the original RAM and replace it with four 4 GB sticks.
I have 8 GB of RAM, and the most I've actually used while playing a game was a little over 4 GB. 6 GB will be plenty, anyway.
