Certainly. In fact, you could switch it to a font that you have and use that during the editing stage. Then, when you get the font you need for final printing.
The only caveat here is that the text is going to reflow when the correct font is finally installed, so you cannot rely on line endings or the number of lines staying the same.
Don’t change anything as far as styles or assigned fonts. Let InDesign do the substitution.
When you open the file on a machine that does have the font, it will automatically work.
Be aware that while you can easily do the edits that under no circumstance should you attempt to anything else such as adjust kerning, tracking or the like since you’re not dealing with the final font. You may also find that copyfit is going to be off as well.
Thank you for your help with this everyone, we will carry on and make our amendments and let InDesign substitute the font when the purchase is FINALLY agreed by procurement! Thank you Bob for the advice about not changing styles or assigned fonts
