Assuming that the linux box is a firewall of sorts (i.e. blocking most
modes of entry), you'd need to devise a secure vpn of sorts between
the w98 box and the linux box so that (1) authentication allows you to
go through the linux box and (2) you could access the internal lan via
SMB or whichever, assuming it is IP or can be encapsulated easily.
Once the (secure) authentication is complete, one setup could allow
the linux box to issue you an ip address local to the internal lan, so
that, via the vpn, you will appear local to the internal lan. That
way, as long as the vpn is good, you have complete access to
everything on the internal lan.
Make sure it's a secure vpn ... otherwise, it'd be somewhat easy to
hijack the connection and compromise internal security.
If you don't have administrator access to the linux box, well, tough
luck. If you don't but some services are already provided, mention
them and possibly we can come up with something.
If you are asking if it's possible to access the internal lan through
a web server (daemon or process) alone, no, I don't believe this is
possible. It may be possible for general file access (though, again,
security is key here), but not if you need to run something on the NT
