I'd agree this probably isn't a great idea, -- it may attract unnecessary attention which would have not already been there. If an attack is automated (where it may not consider the hostname at all) it will have no effect. If it is a targeted attack, the attacker will most likely be well versed in the behaviour of default honeypots. As such if you're machine behaves differently (as it almost always will) the attacker will not be deterred. One example of this includes response time of a failed SSH login -- a HP might reply sub-seconds faster than a real system (especially true in industrial environments).
