I doubt it. LPI cannot isn't like an MCSE (which is all crap btw) or even RHCE. LPI says you know "Linux". What the hell does that mean? Every distribution of GNU/Linux is different. Sysadmin skills required are completely different from ubuntu to Fedora to Suse. No commonality whatsoever. At best you'll know how to do certain stuff like _some_ config files.
It isn't that bad of course - sysadmins regularly move to different distros, but then they use their experience to help them (both on the job and in interviews).
I don't think anyone really cares for the LPI. If you want to appear for some such exam, do an RHCE (or whatever equivalent they have for other distros)
