I have that exact rack. Yes, you can tip the rack and the tailgate (boot) will open. I will warn you that when fully loaded with 4 bikes (Mountain), it can get rather heavy.
If you have a 2014 or newer (i see you have a 2016), the other thing to take into consideration is the auto open on the tailgate. Thankfully, the "anti-pinch" mechanism is pretty good. I had my boot open once when it was on my 08, but as soon as it hit the rack it stopped. No paint damage to the tailgate (phew). Something to be careful of though.
I wouldn't load 4 CF bikes on there. It's a tight fit for 4 bikes, and there will be a bit of rubbing (not much, but it will happen). When I carry my CF road bike, it's never with 4 bikes. You will find yourself arranging pedals and handlebars to make 4 bikes fit on it. It goes, it works great, but it's tight.
