Yeah, with the full version of Acrobat, Load up the Advanced Editing Toolbar.
View > Toolbars > Advanced Editing
Should have a toolbar in acrobat with an arrow select, click on the line of text you dont want. Hit delete.
If it selects more then you want to delete, Use the Text Touchup Tool, Has the Letter T in a box, Highlight the text you want to remove, hit delete.
See if that works
