Yes, there is an interpretation of quantum mechanics known as the "decoherence theory" that suggests macroscopic objects cannot undergo quantum tunneling in practice, or at least, the effects of quantum tunneling become negligible for macroscopic systems. Decoherence theory addresses the phenomenon of quantum systems interacting with their environment, which leads to the apparent disappearance of quantum superpositions and the emergence of classical behavior.
According to decoherence theory, macroscopic objects interact with their surroundings so extensively that the quantum behavior, including quantum tunneling, becomes effectively suppressed and inaccessible to observation. This interaction with the environment causes the rapid and irreversible decay of quantum coherence, making macroscopic objects effectively behave classically.
In this view, while quantum tunneling is a fundamental phenomenon observed at the microscopic level, its effects become negligible and "washed out" by the overwhelming influence of the environment at macroscopic scales. Therefore, macroscopic objects are not expected to exhibit quantum tunneling behavior.
It's important to note that decoherence theory is an interpretation of quantum mechanics and is subject to ongoing research and debate. Other interpretations, such as the Many-Worlds interpretation or certain forms of hidden variables theories, may propose different views on the limits of quantum behavior in macroscopic systems. The precise boundary between quantum and classical realms remains an active area of investigation in the field of quantum foundations.
