pdf's are only small if you can compress the images and text to less
than the original document. Fonts have to be embedded in pdf so if
you use multiple ornamental fonts your pdf will most likely be
bigger. The biggest issue you will face is no option to compress
images well in Word. (i'm assuming there are images in a 2.6MB doc).
Just running some quick tests here on my invoice doc (one page with 2
pictures). (225kb file to start with)
save as PDF from print dialogue: 888kb file
compress PDF option: 278kb file.
PDF-X :888kb
The problem here is i've already compressed the images as much as
possible in photoshop so would require some pretty major work to get
it smaller than 225kb. The pdf options don't allow to determine the
resolution or compression of those two images and hence can't control
the output size very well.
Distiller is the adobe PDF creation tool but i haven't seen what it
can do with word document or if it works at all.
Indesign has some of the best pdf output options so without laying
the document out in the i'm not sure what can be done.

before i had office reinstalled on this machine i managed to open a
work document in imageviewer in 10.4. But can't seem to recreate that
which may have led to more export options.
