The obvious answer is: Read the warranty.
If it is written in baffle-gab, try looking at trigger adjustments. If adjustments are sealed -- epoxied, or fixed -- altering them will almost certainly void your warranty.
In these litigious times, manufacturers attempt to minimize their possible liability by voiding warranties on firearms that have been tampered with, aka adjusted, by anyone NOT authorized by the manufacturer to do so.
You can thank the American Bar Association, and the American public, however you wish.

Savage, I believe, has recently begun selling a rifle whose trigger is specifically intended to be user adjustable.
Your best option is to contact the manufacturer IN WRITING. Ask for an answer IN WRITING.
