Oh yes. Oh yes it is. History has many examples.
Aside from fraud, which is a quick and easy way of achieving what you describe, the cash flow statement is the part of the accounts which has gone through most accounting processes and is therefore the furthest removed from reality.
Additionally, the cashflow is a purely historical statement - it has no predictive capacity. Even at its best, it's only trying to measure liquidity and does not attempt to consider solvency. In other words, a company that borrows more and more money and gets further and further into unsustainable debt will have great cashflow.
In the earlier part of my career I analysed the accounts of many, many hundreds (perhaps thousands) of companies. I never once looked at a cashflow statement.
