The way to do this would be to wrap info fields in conditional statements like this

if member type is X then
    // display info field

Well first you’d need to write some code

// find the user's role
$user = new WP_User( bp_displayed_user_id() );
$role = $user->roles[0];

// find the profile field value you want
$location = bp_get_profile_field_data( 'field=Location' );

// perform a conditional check making sure the user has a specific role and has completed the profile field before displaying the value

if ( ( $role == 'Blah' ) && ( $location ) )
    echo $location;

Notes:

• replace Blah with the role you want
• replace Location with the name of the profile field you want
• I have assumed all of your users have just one role assigned
