Ideally... yes, practically... no. Given the load impedance and the ideal impedance, you can always calculate a transfer function that is exact (simply the path of movement on a Smith chart). However, the question then becomes how good are your measurements? A high performance line section and detector (log amp or other) has at best an error of +/- 1db in linearity and resolution. The step size of the tuning elements adds more uncertainty. Bottom line here is that what seems easy can be difficult.
