Yes you can. BUT there is a huge, glaring issue with this, and it is the reason that NO YOU SHOULD NOT.
Anybody can upload their content as Creative Commons. Which means that they can put a licensed song into their video, they can use someone elses video and upload it. If you accidently stumble upon someone elses work that is labelled as Creative Common but which contains non-licensed content from someone else, then you will also get a strike, have your video pulled etc. And there is almost no way of telling when another creator has done this.
So yes, while you can do this it is highly advised that you do not unless you really know what you are using.
