If you have/can install the Perl modules Archive::Tar and IO::Zlib:

Code:
perl -MArchive::Tar -le'
  ($pattern, $fname) = @ARGV;
  $tar = Archive::Tar->new;
  $tar->read($fname, 1);
  $tar->get_content($_) =~ /$pattern/ 
    and print for $tar->list_files;
  ' d test.tgz

lzegrep

XZGREP(1)							     XZ Utils								 XZGREP(1)

NAME

       xzgrep - search compressed files for a regular expression

SYNOPSIS

       xzgrep [grep_options] [-e] pattern file...
       xzegrep ...
       xzfgrep ...
       lzgrep ...
       lzegrep ...
       lzfgrep ...

DESCRIPTION

       xzgrep  invokes	grep(1)  on  files  which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options
       specified are passed directly to grep(1).

       If no file is specified, then the standard input is decompressed if necessary and fed  to  grep(1).   When  reading  from  standard  input,
       gzip(1) and bzip2(1) compressed files are not supported.

       If  xzgrep  is  invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1).  The same applies to names lzgrep, lze-
       grep, and lzfgrep, which are provided for backward compatibility with LZMA Utils.

ENVIRONMENT

       GREP   If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1).

SEE ALSO

       grep(1), xz(1), gzip(1), bzip2(1), zgrep(1)
