Yes, but note that very old devices will need mainline kernel support before newer AOSP/LineageOS releases can be ported to them. (Of course, this is also desirable as a way of supporting non-AOSP mobile Linux releases there, which are by far the most exciting development in the custom modding scene.) Old downstream kernels don't cut it any more.
are there any examples of such device that got a recent version of LineageOS ported with the mainline kernel? it seemed like there's almost no android phone with mature enough support in the mainline kernel, and most android custom roms just backport needed functionality to old downstream vendor kernels.
