No, that’s not what I am asking. I want to know if wildcard subdomains work at a hosting company (pointed by an A record only) if the main DNS is managed by a domain company.

E.g.

Domain company (DNS managed here)
|
|
v
A record points http://www.example.com and example.com to hosting

If someone puts in test.example.com I assume that request never makes the hosting company? So in saying that the wildcard subdomain setup at the hosting company won’t do anything.
