Please solve the programming task below using a self-contained code snippet in a markdown code block.

In a string composed of 'L', 'R', and 'X' characters, like "RXXLRXRXL", a move consists of either replacing one occurrence of "XL" with "LX", or replacing one occurrence of "RX" with "XR". Given the starting string start and the ending string end, return True if and only if there exists a sequence of moves to transform start to end.
 
Please complete the following python code precisely:
```python
class Solution:
    def canTransform(self, start: str, end: str) -> bool:
```
