Can Taq DNA Polymerase use RNA as a template, and generate false positives in "no-RT" controls?

Taq DNA Polymerase has an intrinsic RNA-dependent DNA polymerase activity (reverse transcriptase activity). However, this activity is very low and is only present under buffer conditions that are completely different from those present during PCR. Therefore, "no-RT" controls would not give false positive results due to reverse transcription activity of the Taq polymerase.
