NO! If your talking about a 100% legit katana, then no. It will ruin the blade. If it is a true katana, take it to a pro for sharpening. If it is a replica, look at the edge. If there is a secondary bevel, then yes, you're fine. If not, use a whetstone and sandpaper (search "how to sharpen a katana" on Google). Your welcome!
