In the case for Snake vs Sam, Grimm and Otacon are always able to provide aid to their partners without ever actually being there via communication devices.

Some characters are also able to straight up summon tools and help, but you have to let common sense tell you whether it's acceptable or not.

Example 1: Tommy Oliver, as a power ranger, is able to call for zords when fighting giant enemies. But there's a difference between calling his mech and calling his friends to actually fight with/for him.

Example 2: If a Naruto character is able to use a summoning jutsu, whatever they can summon with it can be summoned. Regardless of how this unofficial rule works, there would still be nothing physically stopping them from using the summoning jutsu.
