You can always ask but from my experience you will just a get a copy&paste answer with the status from the journal website.

Putting too much pressure (many emails) on the editor might also have negative effects on the outcome of the decision (if the manuscript is a borderline case).

Concerning your specific situtation with the grant application: You can put the paper as "in revision" into the grant application.

@ "Can I ask for the manuscript's status before I'm sent the answer?" - You will just get an answer with the official status. I doubt that they will give away their decision via email before the official decision.
