I think so, at least in some ways. I've shipped a project using PowerShell to script Windows Server/Hyper-V, and it was a pretty pleasant experience. Having a scripting language that not only does typical scripting stuff (wrangling text, etc.) and understands your application's objects is excellent.

Some differences:

* You can actually write your whole application in Elixir, whereas I could not see doing that with PowerShell

* In Erlang/Elixir, instead of objects you have processes. Think of your application as a microservice architecture on steroids, using the Erlang RPC protocol as a means for inter-process communication.

Because each process just sends and receives messages, your script can just send messages to any of the processes that make up your application, as if they were your own service. All you have to do is connect to the remote application using the Erlang Distribution Protocol (to connect different runtimes over the network).
