Use a type known in only one subgraph

Hello 👋
Generally we recommend to use our Community Forums for general questions about the federation.

In Federation v2 you can reference entities without contributing fields. You should define location as not resolvable in your subgraph # 1, i.e.

type Location @key(fields: "id", resolvable: false) {
  id: ID!
}

This will direct the gateway to always resolve the location through the other subgraph. Since Location type is an entity, your subgraph # 2 just have to implement the entity data fetcher and entity type resolver (see: GraphQLConfiguration.java#L22). There is no Location specific data fetcher anymore.
