He wouldn't be able to clobber the UFS partition if he was booted from
it.  So he needs to boot from something else.  Supposing that, then yes,
you could do this.  You'ld need to boot from some other media -- a
bootable USB stick perhaps, or an installer DVD image, the image for
either of which can be downloaded from ftp.freebsd.org
