In the second version, the quotes are passed to the shell as well. In the 
first version, the quotes aren't passed, so that & is interpreted by the 
shell as the put into background operator and the pid part is considered a 
new shell command.
I suspect this would work:
my $junk = `lynx -dump "$url"`;

You might want to look at qx//.
