Can AppleTV be used to display web page on TV?
As far as I'm aware, there is no web browser for the AppleTV as of today; perhaps this will be added as an app for the 4th generation model?

That being said, the only way that I'm aware of displaying web browser contents in the device is to use AirPlay mirroring. From what I understand, any Mac produced since ~2011 should have this ability as long as it is of the Core i5/i7 ilk (the Core 2 Duos can't do this natively).

There is no way for the Apple TV itself to control Safari or any other apps on your MacBook Pro, however there may be an app that could do that for you, I'd check the Mac App Store.
