The game will run, but not well.
The following video demos the game on a laptop with a 5th gen Core i3-5010u and Intel HD 5500 with 2 sticks of 4GB of RAM (8GB total). It runs, but with low FPS.

The good news is that the Intel HD 620 in 7th gen Intel CPUs is a bit more powerful than the Intel HD 5500, but it is still weak compared to a dedicated GPU. It is less powerful than a nVidia 920m. You should see a little better performance than in the above video. If your laptop only has one stick of RAM, then I recommend you install a second stick of either 4GB or 8GB RAM. Integrated graphics can provide around 10% - 15% better performance in games when there are two sticks of RAM installed...
