laptop ram compatibility

In my laptop right now, I have one DDR4 8GB stick of RAM (2133Mhz sodimm). Would one of SK HYNIX 8GB SO-DIMM DDR4 1.2V 2400 work fine in dual channel mode with my existing RAM?

I'm suspecting it might run into issues because of both the fact that mine's at 2133 and that one is 2400 and because the cas is different. Does that make a difference?
