That's not how warranties work in the U.S.. If you do something to Part A, it doesn't void the warranty to Part B unless the manufacturer can prove it did. If you unplug the cellular antenna, that should not affect the physical characteristics of the engine for example. Companies can claim anything they want such as 'warranty void if you remove this sticker' (or not responsible for damage), but that does not automatically make it true. A Supreme Court opinion even said "warranty void if removed" stickers might even be illegal, but they would need a case to come to them before they can determine that.
