I found a few references to where one might find the file which contains the recent project list for older versions of NetBeans but they seemed to be a little dated.  
The file I wanted to find and edit is called projectui.properties
I happen to be on a Mac so that file could be found here:
~//Library/Application Support/NetBeans/7.4/config/Preferences/org/netbeans/modules
I opened the file with a text editor and looked for the project name in the openProjectsDisplayNames entries.  Each of the entries include a dot followed by a number at the end to make them unique.  Once I found it, I noted the number and deleted that line.  
Next I removed the corresponding entries in the openProjectsIcons and openProjectsURLs sections as well.
I have a couple of brute-force suggestions to remove the entire config directory structure (which I have done for other NetBeans issues) but this particular issue was worth a bit more precision.
HTH,
