Unfortunately, the short answer is no, not "the same way".
Windows 7 has gone all Windows Explorer all the time and instead of Network Neighborhood and or My Network Places, you have Network, located bottom left of Windows Explorer. It takes some brief getting use to, but after a while I think you will find it at least as useful as the old way. Like if you change the view to details, you'll be able to see information regarding workgroup membership, location, etc, you can add columns to view additional information as you see fit like discovery method MAC address, IP address, etc.
If all the computers are on the same subnet they should show up here, I have 6 computers Win7 (Ultimate and Pro) and XP pro, with three different work groups, they are all listed and all accessable through this interface.
