Would this memory work on a MacBook Pro (17-inch, Early 2011)? Can anybody tell me if this module: Transcend 8GB 1600MHz DDR3L Unbuffered Non-ECC CL11 204-pin SO-DIMM would work on my MBP? 

My memory specifications currently: 10 GB 1333 MHz DDR3 (1x8GB) + (1x2GB)
I don't know if the 1600 MHz memory would work in that machine, but you can get an 8 GB upgrade that's guaranteed to work in your Mac for less than the product you linked to (click 'View more compatible memory upgrades' to see the single 8 GB module).
