you should be ok if your using a 420 chain. heres what i use for chain refrenceshttp://www.azusaeng.com/chain/mcyclchn.html scroll down to the bottom of the page it tells all the chain dimensions.

Yep, no problems using a 420 chain on a sprocket and adapter designed for 415.

As you can see on that chart, 420 is basically 41 with larger pins. Many here have substituted 41 instead of using 415, chinagirls kits for example.
