Yes – unless you’re stuck on an ancient OS. The 4.8.1 runtime is backwards compatible with any app built for .NET Framework 4.0 through 4.8. It will run without recompilation.
The only exception: if your app explicitly blocks higher runtimes via <supportedRuntime> in app.config, you’ll need to update that entry. .NET Framework 4.8.1 is stable, mature, and likely the last major version of the .NET Framework (Microsoft has shifted focus to .NET 6/8/9). But for millions of enterprise apps still on Framework, 4.8.1 is the recommended endpoint. .net framework 4.8.1 installer
