Sure, a similar setup would be done with VLANs in LEDE. You simply setup the VLANs/IPs, firewall zone and then assign them to the to the proper Switch ports as either Access (untagged VLAN port) or Trunked (tagged VLAN port). I currently do this to create other LANs and guest wireless networks on my device.
