I've heard this before, and as far as I can tell it isn't true. There is an option buried in Device Management that claims to turn on Google Now for Android users but the service it enables is a subset of the full capability of the product. Namely, you get no cards based off of your email inbox. No flight notifications, package tracking, and similar things.
