Probably not.  But you can file a return with $1 of interest income.

https://www.irs.gov/pub/irs-drop/rp-22-12.pdf

If you scroll way down to Section 4, they finally tell you on page 15:

In addition to all other information required to be entered on Form 1040, Form 1040-SR, or Form 1040-NR, a zero AGI filer must enter the following:
(1) $1 as taxable interest on line 2b of the form;
(2) $1 as total income on line 9 of the form; and
(3) $1 as AGI on line 11 of the form.

Ok, but my client received the first half of the ACTC, and now they want to claim the other half but they only have worker’s compensation which is not taxable. Can they still file just to claim the credits or not?

Thank you
