Yes,  GDAL_PDF_DPI is not a creation option of the GTiff driver, but a 
configuration option of the PDF driver.

Configuration options are specified with "--config optionname optionvalue" (note 
: space between name and value, not '=' character)

So : 

gdal_translate --config GDAL_PDF_DPI 300 -co "TFW=YES" addison.pdf addison.tif
