Node.js app and PHP/Apache site on the same VPS2000 hosting

We plan to move from Apache to Node.js server eventually and the question is:

whether is it possible to have Node.js app  and PHP/Apache based site( as API for our Node.js app) at the same VPS2000 hosting account?

Say, the Node.js app will be linked with my-node-js-app.com domain and our PHP API site will be linked with 

my-php-api-app.com domain and all this should work on the same hosting account.

Thanks
