Not really - because the ISO was never intended that way…
@anon89812132 already pointed out that there is no repo on the ISO.
There is some packages on the ISO needed for driver and office installer - packaged in the mhwd.sfs but that is not a fullfledged repo.
The installer unpacks the rootfs and the desktopfs from the live system - and uses the mhwd.sfs as repo to install detected drivers - so theorecically speaking you could rsync the files from ISO in /usr/ and the kernels from /boot into a chroot.
I have no idea how this would pan out on a real system - please let me know 
If I recall correct - didn’t you raise a simliar issue some time ago? Most likely I am confusing this topic with something related.
