I dont really think so. I think depth is more about the web of actions and consequences. Calculation is more a mundane task that dont really add anything and is just the intermediary step between the action and knowing what the consequence is.Yes, but there are some things linked to both. Like the tactical depth being linked to the ability to predict combat outcome.
Let me be more clear. The bonus giving you some increase value in combat power does not need to require complexe calculation to provide depth. The computer can just do that step for you through the UI. You select A and it calculates some bonus. For a boardgame to limit clunkiness its often better to reduce the difficulty of those computation but no depth is lost in the process. For example a biardgame will try to use +1 +2 bonuses rather than percent increases. Limiting the complexity of a computer game computatio can also allow the player to make comparisons more easily that are not provided by the ui.
That way you can even increase the depth by reducing the calculation simply because the player is able to create more intuitive links between a choice and consequences.
