You might be asking based on having heard the theory that fish will grow to the size of the tank, but anyone who knows what they're talking about will give you various versions of the same answer to your question, which is No, you can't. It's sometimes true that the same fish in a smaller body of water will grow to a smaller size than one in a larger body of water, this sometimes translates to tank size, and this sometimes results in stunted fish, but there are limits to it, pure and simple.
Counting on being able to stunt a fish's growth is a bad strategy, very often doesn't work, and it's bad for the fish. The only viable and humane way to keep large fish when you don't have large enough tanks is to keep them while they're small enough, then move them on to someone who can suitably accommodate them when the time comes.
People have different conceptions about adequate tank size and there's room for a difference of opinion, but there are definitely limits, it has to be within reason. The basic principle is you need a tank that fits the fish, you just can't force a fish to fit a tank that's multiples smaller than what it needs. There are just so many reasons this is true.
Buying fish small, keeping them a while, then moving them on doesn't always work, some are niche species with a very limited market, making them difficult to rehome, but aros are popular enough ime that you can typically find a home for them. In fact, there was a time I kept aros myself and this is what I did for a while. I didn't try to profit, didn't try to keep them too long in my tanks, and didn't do if for very long, but for a while it was a way to experience a fish I liked.
