DJVU format is a very good format both in terms of file size an readability.
Is there a way that I can read DjVu files on a 4th generation Kindle?
There is no out of the box possibility.
The easiest way would be to convert the file to pdf, of course this would make the DjVu advantages disappear.
The alternative is to modify your Kindle by installing a compatible reader. One possibility that is still actively developed is Librerator (which is also a superior for viewing larger pdfs). You will however have to jailbreak your Kindle and install KUAL, which will possibly void warranty.
What I always do to read DjVu ebooks on my Kindle is the following (In case they do not contain important images).
Like that you have the freedom to adapt font size etc.
You can use Duokan. It is available for Kindle 2, 3, 4, 5 and DX versions.
It's upgrade and it's safe.
The extension allows Kindle to work with EPUB, CHM, DOC, TXT, ZIP, RAR, JPG, PNG, BMP and DJVU formats.
Supports fonts in ttf format.
I achieved it with using DjVuLibre
If you install the

.ps. You can then use any tool (like
ps2pdf) to turn that
.ps into a
Full command sequence
djvups original_file.djvu temp.ps ps2pdf temp.ps outputfile.pdf rm temp.ps
In my experience using
djvups is much faster than using ImageMagick's convert, and uses much, much less memory.
The conversion to
.ps quick, but the conversion to pdf step can take longer.
The pdf (and ps file) is much larger than the .djvu file (about 100 times the size)
Finally, you can use PDF file or convert it to

Another solution is to use Calibre and after installation:
Add book -> right click on it -> select
