Conceptually, sure. Implementation-wise, no.

And then, on current GNU/Linux systems, it is not a PIE.

Because without PT_DYNAMIC and PT_INTERP, on current GNU/Linux systems,
the executable won't work.
You seem to be speaking at some sort of conceptual level. At the
conceptual level, you are correct. It is possible to define some sort
of static PIE. But there is no such thing today, and implementing it
will require changes to the linker. When it is implemented, we will
change the linker such that -pie -static is not an error.
