Yes. Although both the tetrahedral and see-saw shape have four atoms bonded to the central molecule, the lone pair in the see-saw shape causes the difference in name. Every VSEPR structure (AX4 vs. AX4E1) has a different shape name.
When determining the molecular shape, we consider the influence of the lone pairs on the shape, but when naming we only look at the positions of atoms. For example, in NF3, the atoms and lone pair would form a tetrahedral shape. But since we don't consider the lone pair on the N while naming, the shape is actually trigonal pyramidal.
