As i have answered under question, it's not certain if you can or not but if one of you gets banned from Play Store, other associated account will get banned eventually. It's not that uncommon to get banned even without knowing why. It does not worth taking that risk. There are other ad networks like FAN, StartApp, Heyzap and more, your Play Store account worths a lot more than that since it's for good.
I got banned and my whole income was from Play Store and all gone now. They also stop publishing ads in my apps because my apps removed from Play Store(they are valid apps with no issue regarding to publisher policies) even if those apps are published and still available on other markets.
