Yes, thats possible:

in the child component you have to declare a p:remoteCommand that executes the child component logic. The name of this remoteCommand should be defined by a component interface attribute:

< cc:interface componentType="IvyComponent">
  < cc:attribute name="callbackName" />
< /cc:interface>
< cc:implementation>
  < p:remoteCommand name="#{cc.attrs.callbackName}" actionListener="#{logic.execMyComponentLogic}"/>
< /cc:implementation>

The parent dialog can then embedd the component-dialog and define the name of the child callback method. And bind it to an oncomplete action of a commandButton:

< ic:jsf.call.child.logic.ChildDialog callbackName="callChild" />
< p:commandButton value="call child logic" oncomplete="callChild();"/>
