How I Got a Truly Anonymous Signal Account (theintercept.com)

Yes, you can use Signal without sharing your personal phone number. Here’s how I did it.

tl;dr the sms verification falls back to voice and they just used a payphone.

I guess if you count the airport full of cameras they went to to do this as "anonymous", then sure :)

Also this article from 2017 suggests not using this method:

It’s important to maintain control of this phone number. For example, you could use a disposable SMS service to register with Signal — there are many such services if you search for them — but those phone numbers can be used by anyone. Similarly, you should avoid using a public payphone’s number, or a SIM card on which you do not intend to renew service. If someone else can receive SMS messages or phone calls to this phone number, they can take your Signal account away from you.

That risk is not just theoretical. I made a test account (on another service; not Signal) using a free anonymous SMS number. A few months later, the account had been hijacked.

Of course, if it's a disposable account, then having it hijacked after you're done with it might be a good thing.

Signal has account pins now so I don't think the attack vector is as large as it used to be
