Yes, that should work. What

Yes, that should work. What will happen:

  1. Host A sends a packet which is received without vlan tag on the access-port in vlan 10.
  2. The switch forward the packet on the trunk without vlan-tag because 10 is the native vlan.
  3. Switch 2 receives the packet without a tag and interprets it as belonging to vlan 20.
  4. Host B can receive the packet because the access port connecting host B is also in vlan 20.

For sure it should. And using something like this in production is most likely a misconfiguration and a potential source of many problems.

But when learning Vlans, these are questions that should be understood.
