I don't think either one of them should have any problems getting it to run. But the game
may not perform very well.

Laptops are just not very good for gaming. But if you are able to run EUIV without any lag, I would expect HOI4 to run on the lowest settings. If it does lag with EUIV it will probably be much worse for HOI4.
Like others have said, going through Steam is your best bet. As soon as you download it, play as Cuba or some small nation. Turn off fog of war. Set speed on max so you can get in to the late game within the 2 hour window and see how bad it lags.
Good luck.
