Answer 1

Can I add any random attribute to 'window' object in javascript?

Yes, just like you've shown.

Does it have any side effects with any libraries?

No, not unless you use a library which sets a property you then overwrite.

And is it cross-browser compatible?

Yes, completely.

Having said that, this practice is generally frowned upon. You could end up overwriting something you don't want to.
