man 8 dhclient says:
The  client  normally  doesn't  release	the current lease as it is not
required by the DHCP protocol.  Some cable ISPs require	their  clients
to  notify  the	server if they wish to release an assigned IP address.
The -r flag explicitly releases the current lease, and once the lease
has been released, the client exits.

So you may need to do whatever is your Linux version of dhclient -r

The DHCP server has already assigned a lease to Linux which FreeBSD
knows nothing about.
