All current "working and marketable" linux phones are built on top of android currently for compatibility with that existing market, so it depends how detached from android you want to be. (To my knowledge. Id love to be proven wrong)
If completely, then no.
Better bet is an android OS that has everything ripped out of it and privacy hardened. Its the same thing the linux phone is doing but without the linux portion sitting on top.
Otherwise you can attempt to use a pure linux setup but it's going to be rough unless youre already set on dropping creature comforts.
Knowing what dork used to actually "mean", they really said "dickbutt" in a headline huh.
