edited Jun 25, 2019 at 23:51For all practical purposes, and in a machine learning context, these two terms are treated as synonyms.
The term "residual" is due to the origins of linear regression from statistics; since the term "error" in statistics had (has) a different meaning that in today's ML, a different term was needed to declare the difference between the estimated (predicted) values of a dependent variable and its observed ones, hence the "residual".
You can find more details in the Wikipedia entry for Errors and residuals (notice the plural); quoting:

The use of the term "error" as discussed in the sections above is in the sense of a deviation of a value from a hypothetical unobserved value. At least two other uses also occur in statistics, both referring to observable prediction errors:
