Is there any way apple can find out if I swap screens on iphone 5?

I have an iphone 5 with a cracked screen and another one with a perfectly good screen but some other issues that made it useless.
I wanted to swap the screens on the two so that one that is working gets the good screen but I wanted to know if there's any way apple is gonna find out that the screens have been swapped and void my warranty.
I know how to swap the screens, I have done it before, just wasn't clear on the warranty thing.

Yes, because some of the screws you need to remove are covered by warranty seals, some of which also double as moisture tell-tales. Even if you buy replacement replica seals there will usually be witness marks left behind by the tools used to dismantle the phone.
