No, I understand that you can use the IPA freely, but using a chart from a college textbook is very different. That's the 1993 edition of Language Files by Ohio State University.
And that textbook is itself copying the chart from the International Phonetic Association: http://www.langsci.ucl.ac.uk/ipa/fullchart.html Ohio State University did not create that chart. (I haven't seen the textbook, but am assuming from your description of it.)
The International Phonetic Alphabet is copyright the International Phonetic Association (Department of Theoretical and Applied Linguistics, School of English, Aristotle University of Thessaloniki, Thessaloniki 54124, GREECE): http://www.langsci.ucl.ac.uk/ipa/fullchart.html The International Phonetic Alphabet may be freely copied on condition that acknowledgment is made.
