The simple answer is no.
The simple answer is yes.
You asked two diametrically opposed questions! 
The privacy component derives the basic user data from the wp_user table, specifically the ID field. The BuddyPress xprofile tables all refer back to this particular field to relate their record-level data. So, in essence, there should not be any issue if you disable the xprofile component.
