Domains are not linked to technologies, they are just names that lead to an IP address. So right away we can conclude that there is no problem.
Hence the question about can put two different technologies in the same IP.
An IP can only be on one device, so we have to know if it’s possible to have both technologies on the same server. And the answer is yes, you can on both Windows and Linux.
Windows supports ASP.NET MVC and PHP running on the same site, there is no specific technical restriction on using both. In general people use IIS for this, but nothing prevents them from using Apache, although their hosting probably doesn’t offer this.
Linux is also possible to run both. ASP.NET MVC can run through the Mono or of .NET Core, what should be more advantageous nowadays (in fact Mono is being discontinued as a complete product), but I don’t know how much these two solutions work in your hosting. They may not work.
So it does, but your stay may not be ready. What’s more, there may be conflicts between the two parties. Not by technology, but how the application was developed. These things we have no way to answer.
Probably, changing the hosting to Windows, should work smoothly

But I get that in a single domain?

I don’t know if a single domain would be quite the solution. I would advise using a subdomain for this, such as... http://www.meusistema.dominiodosite.com. If that’s not the case, what you can do is create a path forward, like http://www.dominiodosite.com/meusistema. Apart from these two paths, you cannot use the same domain
