It gets teleported. So it doesn't matter if i summon it from 5 KM or 2000 KM. Time-Space is totally different. And dimensions doesn't affect the teleportation. That's not what i meant. Summoning bigger things takes more chakra. Summoning things from further away requires more chakra. So if you can summon a big thing from nearby ( say a snake from the Cave to the 4th war), then you could summon a small thing (say a hawk) from far away (say, another dimension). Given that Sasuke's chakra had gotten more powerful (Rinnegan), and that he got more (Mark with Hagoromo's chakra), i don't see why he couldn't summon the snake easily. Doesn't mean normal ninja can.

Summoning is listed as space-time. So is Kamui. The basics are the same. Hagoromo needed all the previous Kage to summon Team 7 back to the Ninja world, so obviously it wasn't something that could easily be done.
