Some other definitions of phylactery
"(in the early Christian church) a receptacle containing a holy relic.
an amulet, charm, or safeguard against harm or danger."
And if you go back to the Greek origin, phylaktḗrion, from which phylactery is ultimately derived, it not only includes amulets tefellin and safeguard, but a guarded place.
Yeah, but the thing here is "in the early Christian church". The thing is that language has evolved past that in the same way using synagogue would refer to a Jewish temple and generally not a "congregation".
Did Pathfinder change the phylactery? I never paid it attention when looking at PF 1e. From AD&D to 3e, the phylactery was where the lich stored its own soul for protection. If that is no longer what it does in Pathfinder, then, yes, I see why phylactery would not be appropriate.
I'm not sure why the definition of a soul storage unit is really appropriate, given the actual usage of the word.
