SLI requires two Nvidia GPUs, so no if it is a laptop.
SLI was never impossible on a laptop. The Gigabyte Aorus or Giabyte Aorusv2 also has SLI. In fact with a 860M SLI.
I didn't think you could add a second GPU to a laptop. I knew that they had ones that came with two GPUs default.
Laptops are hard to customise with all the wiring and stuff. So he would need be a laptop expert (a really good one) to be able to put SLI in, but if the case can fit both of it and the PSU will support it.
