There are no such restrictions.

In packet mode JUNOS the default is to allow telnet to any interface on the
box.  If you're running SRX or J-Series (with secure flow mode) the default
is to deny telnet on any interfaces.  You would need to configure
host-inbound-services under the respective zone or interface to allow telnet
access on those interfaces.
