NO!, simple as that, why? The Amiga when it was designed, was designed to use electrolytic capacitors in those particular circuits because they are fit for purpose, they have the correct characteristics required for that circuit and the circuit they have been installed in take in to account that.
When you replace the electrolytic capacitors with Tantalum ones these have different characteristics and thus you change the circuit. And yes Tantalum’s do not leak and may look very nice soldered on the board however unlike electrolyte capacitors, when Tantalum’s fail they do so with a bang and its far easier to repair leakage than a burnt board.
Below is one example of a Tantalum exploding in an Amiga.
