Hi Verity25,
yes. InDesign CS version 3 documents can be opened and worked on with InDesign 2020 version 15.
FWIW: There is no way back to InDesign version 3.
( Unless you have access to InDesign CS4 version 6 which is able to open IDML files exported from InDesign 15 and can export INX exchange files one can open with CS3 version 5, or, with some manual editing, then can be opened directly with InDesign 3. )
