Like my home IP address or my e-mail address, I believe my full name is not very private data. If it allows people to know that I own an iThingy, or to relate my surname to my MAC address, then so be it. I accept this is not private data, I do not use my surname or email as a password.

Calling you computer "Fitzgerald John Kennedy's MacBook" will not reveal any critical information about you.

If I prefer to enforce my own naming conventions (which do not reveal my name), it is mostly because I love naming things myself, and making up naming rules.

If you are looking for a better way to name a laptop/smartphone, please define the "goals" of naming.
