Probably yes:
loadplugin Mail::SpamAssassin::Plugin::ExtractText
/etc/spamassassin/init.pre:#loadplugin 
Mail::SpamAssassin::Plugin::ExtractText

/etc/spamassassin/PDFInfo2.pm:and enable it using the 
L<Mail::SpamAssassin::Plugin::ExtractText|https://spamassassin.apache.org/full/4.0.x/doc/Mail_SpamAssassin_Plugin_ExtractText.html> 
plugin.
/etc/spamassassin/PDFInfo2.pm:        must be extracted by another 
plugin such as ExtractText.pm

for SA4.x
