There isn't one in Kea 1.2, but there will be in 1.3. They will be
called lease{4,6}-del. See here: http://kea.isc.org/wiki/Commands for a
high level overview.

Writing to the lease file from external sources while Kea is running is
just asking for troubles. You can tweak (and in particular delete a
lease) a MySQL or PostgreSQL DB while Kea is running.
