RedHat Do I need to extract the entire tar file to confirm the tar folder is fine?

I would like to confirm my file.tar is been tar-ed correctly before I remove them. But I have very limited disc space to untar it.
Can I just do the listing instead of actual extract it? Can I say confirm folder integrity if the listing is sucessful without problem?

tar tvf file1.tar


tar xvf file1.tar

tvf switch should suffice but you can always untar it to another machine via ssh in this manner..
Of course, you will need space on that other host.
cat yourtar.tar | ssh newhost "cd /restorefolder && tar xvf -"
