The second tar knows nothing of the first tar so can't find the file. To get a file out of a tar you have to extract it. You can make it print to stdout with -O, and extract the other one from there:

Code:
# list files inside inside.tar.gz, which itself is inside file.tar
tar -O -xf file.tar inside.tar.gz | tar -ztf -

I don't think you can list files in file.tar and extract files from file.tar in the same call to tar, you may want to save the list to a temp file and operate on it from there.
