Can I make a creature target itself?

Hypnotism (Heroes of Fallen Lands p205):

Hit: […] The target uses a free action to make a melee basic attack against a creature of your choice[…]

Friendly Fire (Dragon 384):

Effect: The target repeats the attack as a free action against a creature you choose within 2 squares of the target of its original attack. The new target must still be legal for the attack.

Can I make the target of Hypnotism or Friendly Fire target itself with the MBA?
