Tricky question: directly? No. Indirectly? Yes.

Tolerance to a drug or substance occurs when the body adapts to regular doses and results in more of the drug or substance being required to achieve the same effect. So a regular drug or substance user may be able to take higher doses without overdosing. (Although tolerance won't prevent overdoses where the strength of the drug has increased without the user's knowledge and they don't lower the dose or from users making excessively large dose increases.)

But, many overdoses occur when users have a lowered tolerance to the drug or substance. This most often occurs when the user stops using for a period of time and then resumes using again with the same dose. As their tolerence has decreased, their previous safe dose can be too much and result in overdose. This is the cause of a large number of heroin overdoses: users stop for a while then use the same amount they previously could handle.

If someone hasn't used a drug or substance for any length of time, they should always use a smaller amount to reduce their chance of overdose.

Is a drug user who has developed a high tolerance to a drug could take an overdose large enough to cause death?

Drug toxicity mean the degree to which a drug can harm humans or animals. Toxicity may well occur in the recommended dosages. On the other hand, overdose means taking an excessive amount. They are not the same since toxicity may occur without overdose although overdoses often lead to toxicity.
