This copy of Unix v4 came from AT&T and not one of the freely licensed ones Caldera released. Caldera may own the rights now for this unearthed copy, but I am not aware that they have provided licenses for this new release.
If your argument is that Caldera might not actually have the rights to UNIX in the first place to grant the license, that's fair.
But the license they provided (http://www.lemis.com/grog/UNIX/ancient-source-all.pdf) explicitly names versions 1, 2, 3, 4, 5, 6, and 7 of UNIX for the 16-bit PDP-11. Yes, these versions originated at AT&T (Bell Labs) but are distinct legally from SysIII and SysV UNIX, also from AT&T, which are explicitly not covered by the Caldera license.
