Well, not as a root file system. You can boot into a small RAM disk and set up a ppp link, though.
Actually, it is possible to mount the root FS via NFS over PPP. We have done so for development purposes on some of our systems with no ethernet service ports. The performance is limited, but once a binary (and it's associated libraries) are cached into memory, the system is reasonably responsive.
The trick is to use an initrd with a linuxrc file that sets-up the PPP link. The "root=" command line argument should be "/dev/nfs" and either an "ip=" or "nfsroot=" line should be used. I can be more specific if someone wants more information.
