There is data recovery software you can use.
If you still own the hard drive that you had installed the WoW client on, you can run the data recovery software on it, and it will retrieve your client as well as the WTF folder containing your account name.
This process can take a long time and depending on software used, might be annoying to shift through all deleted files to find the one you need.
