What's wrong with the SODIMM you have crossed out?
So you bought the 8GB SODIMM kit I recommended in my first post?

Lenovo's home page for it is here:
So in theory you can add up to 16GB in 2 x 8GB SODIMMs. For 4GB then the Crucial kit left of your big red cross would be my recommendation (DDR4-2666)
But unless you're intending to only run a 32bit operating system the 8GB kit in the link above is far better value
