Depends on circumstances. MUI means that your spell can have multiple active instances without causing any undesired behaviour. That doesn't neccessarilly mean that it has to be cast by different units - it can be one and the same unit!
For example let's say your spell places a 15 second debuff on the target. The spell's cooldown is 3 seconds.
Even if your hero is the only unit in game using this spell, if he casts the spell while another instance of the spell is already active (= some unit is already debuffed by it) and that spell is not MUI, an undesired behaviour will happen.

it depends on what spell, really.

(horrible) example:
spell fires a really slow projectile to target and the spell has no cooldown. if the spell is cast again, the triggers will stop using the first projectile and use the new one.
 
Is it possible to use non-MUI spells on multiplayer maps as long as units don't have the option to have the same abilities as the other units?

Yes, it is possible under the following conditions:
  • Other units do not have that same ability
  • The ONE unit that does have the ability is unable to cast that same spell more than once in one instance
  • The spell uses unique variables that will not cross over with other triggers
It is also not needed for spells to be MUI if they are practically instant, as others have stated.

@Nichilus What do you mean about such undesired behavior? Give examples.

Undesired behaviors can include the first spell instance stopping before it actually finishes, effects not being destroyed, dummies not being removed, etc because a new one has started.
