Can ArgoUML read an MDL file generated by Rational Rose?
No. MDL is a Rational Rose-specific format. You are much better off getting Rose to export an XMI file.
Rose has an add-on that can create XMI format from an MDL file that is available here.
You will then need a tool like UML/Tool (available at umltool.d-a-t.com) to convert that .XMI to a version that ArgoUML understands.

I've read a lot of accounts that TCC is an excellent UML modeler, compared to Rose, but it is a Java Swing app that hordes memory like crazy.
