Yes, there is a way.
When you click on an icon for Konqueror, it also specifies what profile to use.
For the icon that launches Konqueror in the Web Browser profile, the command given is
kfmclient openProfile webbrowsing
or for File Management
kfmclient openProfile filemanagement
I believe, if you edit the properties of your icon so it gives this command
kfmclient openProfile midnightcommander
you should then get the midnight commander (I haven't tried it, but I presume it will work)
Or you can create a new aplication link with the above command.
Hope that helps.
