Macbook had logic board replaced twice, should I remove the old ones from my iCloud account?

My MacBook Pro 16 had the logic board replaced by apple twice as part of the warranty, so now in the Apple ID settings I see the new Mac,my iPhone, and two other Macs with the same serial number (the two old logic boards basicly), should I remove them or it doesn't matter ? Kinda paranoid with someone having access to my data.

PS : Find my was deactivated before the Logic board could be replaced on both of them.

Solution 1:

There is no downside to removing them - so if only for aesthetic purposes I would recommend it.

That being said, there's also little chance of any problem arising from leaving them on your account. If the board was replaced, it doesn't work anymore - and the authorization likely relies on the contents of the hard drive to be useful.
