I think Apple will not care about this.
1. Apple did not "invent" the silver body with black keyboard and black hinge design (my Vaio Z1 from 2003 had that already)
2. There are enough "differences" to make a lawsuit fail, e.g. the touchpad is not centered, the bezel is not flush with the screen (ugly!), and there might be other differences that are not visible in the screenshot.
The problem is that once you decide to have an aluminum body with black chiclet keyboard, you can only do so much to not look like a MBP.
Of course copying more details like the hinge design and the power button doesn't help here, and really paints a bad picture for Lenovos design department.
In the end, I see this more as something to make fun of, and less as something to get upset about
