You can have this gesture, but not while using an app. That's because this would interfere with scrolling or possible app gestures.
I have the exact gesture set to open recent apps with Nova Launcher.
Install Nova launcher, go to Nova settings, gestures and buttons and set the swipe up gesture to open Recent Apps.
This will work when you are on one of your home screens, but not in apps, like I said.
Hope this helps.
