Is it allowed to add a UITabBarItem that opens up Safari?

I want to add a UITabBarItem on the TabBar which when clicked opens up Safari instead of loading its corresponding tab. (Not UIWebView but the app goes to background and opens up Safari instead)

I already know how to do this, but I was wondering if this is allowed by Apple. I know they're OK with using the TabBarItem to trigger other actions such as opening a modal in the app, etc. However I am not sure if it's OK to open a safari.

I am just being cautious because I don't want it to get rejected for this and wait another week.
