A pax archive created on AIX will be most probably be extractable on Linux. You could just try it out with a very small archive yourself.
If you can use the extracted contents on Linux depends on them.
If a FS backup can be restored on Linux depends with which tool you did it on AIX, if it is available on Linux and is compatible. If you can use the restored contents, depeneds, again, of what that is.
Generally: If it is executables you restore, they will not be able to run on Linux. If it is just a DB backup and the RDBMs is the same on AIX as on Linux, you will be most probably be able to import it on Linux. Same for simple CSV files or something like that.
A VG backup or any backup based on AIX's LVM will not be able to restored on Linux. You don't even have the utilities there and the LVM of Linux is not the same as on AIX.

vgcfgrestore
VGCFGRESTORE(8) System Manager's Manual VGCFGRESTORE(8)
NAME
vgcfgrestore - restore volume group descriptor area
SYNOPSIS
vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName
DESCRIPTION
vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup. You can specify a
backup file with --file. If no backup file is specified, the most recent one is used. Use --list for a list of the available backup and
archive files of VolumeGroupName.
OPTIONS
-l | --list -- List files pertaining to VolumeGroupName
List metadata backup and archive files pertaining to VolumeGroupName. May be used with the -f option. Does not restore Vol-
umeGroupName.
-f | --file filename -- Name of LVM metadata backup file
Specifies a metadata backup or archive file to be used for restoring VolumeGroupName. Often this file has been created with vgcfg-
backup.
See lvm for common options.
REPLACING PHYSICAL VOLUMES
vgdisplay --partial --verbose will show you the UUIDs and sizes of any PVs that are no longer present. If a PV in the VG is lost and you
wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate) to
initialise it with the same UUID as the missing PV. Repeat for all other missing PVs in the VG. Then use vgcfgrestore --file filename to
restore the volume group's metadata.
